A headache can occur in any part of the head; one side of the head or both sides. Sometimes a headache can also occur in the front of the head or back.

Causes of headaches

The International Headache Society categorizes headaches into two types – Primary and Secondary.

Primary headaches are standalone illness and are caused directly by chemical changes in the brain. Factors that lead to primary headaches include tension, migraine, and injury.

Secondary headaches are the result of other disorders. They are the symptoms which take place when other conditions stimulate the nerves in the head which are sensitive to pain. There are several factors that contribute to headaches. Some of these include:

Alcohol-induced hangover

Blood clots

Brain tumor

Stroke

Influenza

Glaucoma

Concussion

Panic attacks

Brain freeze

Sleep deprivation
